Paint Ground Wire

My wife and I are updating our dining room and decided to spray paint the chandelier rather than replace it (surprisingly, this actually looks pretty good.) After doing, we realilzed we had also spray painted the ground wire that runs up the chain to wire box in the ceiling.

Question: Do you think the spray painted ground wire represents any type of risk? I can't believe the paint would interfere with its conductive properties in case of a short but I don't have a lot of experience in this area. Any thoughts?
